Result of possible unsuccessful hacking attempt.

Thanks Shawn, I don't have access to logs on this hosting setup. I had moved the site to this host a few months back so it was up-to-date from a clean install without any old plugins

Thanks Hameau, hostroute, generally good ime and yes, that was the code I was looking for. I must put it somewhere safe.

A day after the initial panic of locked down site I am almost certain it was a false alarm. None of it makes any sense and the site seems totally unaltered. Since I only have a very limited dashboard / ersatz control panel there isn't much I can do to check. I am hoping it just won't happen again.
